django - 使用DJango DetailView的发布请求给出错误 'MyView'对象没有属性 'object'

Question

我正在尝试使用Django DetailView创建一个对象。我的代码就是这样。

class Detail(DetailView):
    model = MyModel
    template_name = 'mymodel_detail.html'

    def get_context_data(self, **kwargs):
        context = super(Detail, self).get_context_data(**kwargs)
        context['form'] = DetailForm
        return context

    def post(self, request, *args, **kwargs):
        form = DetailForm(request.POST, request.FILES)
        if form.is_valid():
            context['reply_form'] = DetailForm
            self.object = super(Detail, self).get_object()
            context['object'] = super(Detail, self).get_object()

            return self.render_to_response(request=request, template=self.get_template_names(), context=context)
        else:
            context = context = super(Detail, self).get_context_data(**kwargs)
            context['reply_form'] = form
            self.object = super(Detail, self).get_object()
            context['object'] = super(Detail, self).get_object()

            return self.render_to_response(request=request, template=self.get_template_names(), context=context)

但是在这里我得到了错误

'Detail' object has no attribute 'object'

我尝试在上下文实例中以及与self一起分配对象。但是什么都行不通。

这里缺少的是，您必须在调用get_context_data()之前将对象分配给类或self。

class Detail(DetailView):
    model = MyModel
    template_name = 'mymodel_detail.html'

    def get_context_data(self, **kwargs):
        context = super(Detail, self).get_context_data(**kwargs)
        context['form'] = DetailForm
        return context

    def post(self, request, *args, **kwargs):
        form = DetailForm(request.POST, request.FILES)
        if form.is_valid():
            # Write Your Logic here

            self.object = self.get_object()
            context = super(Detail, self).get_context_data(**kwargs)
            context['form'] = DetailForm
            return self.render_to_response(context=context)

        else:
            self.object = self.get_object()
            context = super(Detail, self).get_context_data(**kwargs)
            context['form'] = form
            return self.render_to_response( context=context)

并在 render_to_response()中传递上下文。没有其他参数。
希望它能为您服务。
